Description

超音波シャワー洗浄装置Ultrasonic shower cleaning device
 本発明は、洗浄液に超音波振動を印加して洗浄する超音波シャワー洗浄装置に関し、特に、超音波振動を効率よく流路の洗浄液に印加して、洗浄液を拡散させることなく被洗浄物にスポット状、ライン状に照射可能な超音波シャワー洗浄装置に関する。 The present invention relates to an ultrasonic shower cleaning device for cleaning by applying ultrasonic vibration to the cleaning liquid, and in particular, the ultrasonic vibration is efficiently applied to the cleaning liquid in the flow path to spot the cleaning liquid on the object to be cleaned without diffusing the cleaning liquid. The present invention relates to an ultrasonic shower cleaning device capable of irradiating in a line shape.
 従来、超音波洗浄装置は、洗浄槽の下面に超音波振動子を取り付け、洗浄液を洗浄槽に供給して、洗浄槽に被洗浄物を浸漬して、超音波振動を洗浄槽の下面から印加して洗浄を行うのが一般的である。 Conventionally, in an ultrasonic cleaning device, an ultrasonic transducer is attached to the lower surface of a cleaning tank, a cleaning liquid is supplied to the cleaning tank, an object to be cleaned is immersed in the cleaning tank, and ultrasonic vibration is applied from the lower surface of the cleaning tank. It is common to perform cleaning.
 また、液晶パネルや半導体ウェーハ等の洗浄には、洗浄液に超音波振動を印加し、超音波振動を印加した洗浄液をシャワー状に噴出させ、これらの被洗浄物を超音波洗浄するシャワー型超音波洗浄装置が知られている。 For cleaning liquid crystal panels and semiconductor wafers, ultrasonic vibration is applied to the cleaning liquid, and the cleaning liquid to which ultrasonic vibration is applied is ejected in a shower shape to ultrasonically clean these objects to be cleaned. Cleaning equipment is known.
 例えば、特許文献1には、ノズル先端から被洗浄物までの距離調整を厳密に必要としない、設置調整が容易なスポットシャワー型超音波洗浄装置が開示されている。スポットシャワー型超音波洗浄装置は、ノズルから超音波が印加された洗浄液を被洗浄物に噴出することで、パーティクルなどの汚れを除去するものである。 For example, Patent Document 1 discloses a spot shower type ultrasonic cleaning device that does not require strict adjustment of the distance from the tip of the nozzle to the object to be cleaned and is easy to install and adjust. The spot shower type ultrasonic cleaning device removes dirt such as particles by ejecting a cleaning liquid to which ultrasonic waves are applied from a nozzle onto an object to be cleaned.
 特許文献1によれば、スポットシャワー型超音波洗浄装置は、筐体の先端部に取り付けられたノズルと、ノズルの後端部に対向して配置された円板状の超音波振動子と、筐体の側面に形成された洗浄液の給液口とを有し、ノズルの吐出孔を直径が一定の直線状丸孔に形成している。 According to Patent Document 1, the spot shower type ultrasonic cleaning device includes a nozzle attached to the front end of a housing, a disk-shaped ultrasonic vibrator arranged to face the rear end of the nozzle, and the like. It has a cleaning liquid supply port formed on the side surface of the housing, and the nozzle discharge hole is formed into a linear round hole having a constant diameter.
 給液口から供給された洗浄液に超音波振動子から放射された超音波を印加してノズルの先端から洗浄液を噴射してノズルの前方に配置された被洗浄物を洗浄する。これにより、ノズルから放射される超音波が焦点を形成しないため、被洗浄物からノズル先端までの距離を厳密に調整する必要性がない。 Ultrasonic waves radiated from the ultrasonic vibrator are applied to the cleaning liquid supplied from the liquid supply port, and the cleaning liquid is sprayed from the tip of the nozzle to clean the object to be cleaned placed in front of the nozzle. As a result, the ultrasonic waves radiated from the nozzle do not form a focal point, so there is no need to precisely adjust the distance from the object to be cleaned to the tip of the nozzle.
 また、特許文献2には、液体を容器の吐出口から流出させて被洗浄部位と接触させることで超音波の伝播路を形成し、生体などの被洗浄部位を超音波振動で洗浄するようにしたノズルシャワー式の超音波洗浄装置が開示されている。 Further, in Patent Document 2, a liquid is discharged from a discharge port of a container and brought into contact with a portion to be cleaned to form a propagation path for ultrasonic waves, so that the portion to be cleaned such as a living body is cleaned by ultrasonic vibration. A nozzle shower type ultrasonic cleaning device is disclosed.
 特許文献2によれば、ノズルシャワー式の超音波洗浄装置は、一端部側に超音波振動子が取付けられ、他端部側の端面が超音波放射面となる超音波伝達体を、超音波放射面の近傍で、弾性体から成るOリングなどの保持部材によってハウジングの内周面に気密に保持固定する。したがって、保持部材によって放射面の側面での超音波振動を抑制しないようにしつつ、超音波伝達体の保持を可能としたものである。また、超音波伝達体の側面や超音波振動子の部分が液体と接触することを防止でき、高効率化を図っている。 According to Patent Document 2, in the nozzle shower type ultrasonic cleaning device, an ultrasonic transmitter having an ultrasonic vibrator attached to one end side and an end surface on the other end side serving as an ultrasonic radiation surface is an ultrasonic wave. In the vicinity of the radial surface, it is airtightly held and fixed to the inner peripheral surface of the housing by a holding member such as an O-ring made of an elastic body. Therefore, it is possible to hold the ultrasonic transmitter while preventing the holding member from suppressing the ultrasonic vibration on the side surface of the radiating surface. In addition, it is possible to prevent the side surface of the ultrasonic transmitter and the portion of the ultrasonic oscillator from coming into contact with the liquid, and high efficiency is achieved.
 また、特許文献2には従来技術として同文献の図12に振動伝達体がケーシングの外部に露出している超音波洗浄装置が開示されている。この従来技術は、同文献の段落「0007」にも記載されているように、容器中の水に浸した被洗浄物の被洗浄部位に超音波洗浄装置の振動面を直接接触させて、数十kHz程度の超音波の振動エネルギによって、汚れを除去している。即ち、この従来技術では、スポットシャワー型超音波洗浄装置と異なり、超音波振動を行っている振動面を被洗浄部位に直接接触させて洗浄を行っている。 Further, Patent Document 2 discloses, as a prior art, an ultrasonic cleaning device in which a vibration transmitter is exposed to the outside of a casing in FIG. 12 of the same document. As described in paragraph "0007" of the same document, this prior art is performed by directly contacting the vibration surface of the ultrasonic cleaning device with the site to be cleaned of the object to be cleaned soaked in water in the container. Dirt is removed by the vibration energy of ultrasonic waves of about 10 kHz. That is, in this conventional technique, unlike the spot shower type ultrasonic cleaning device, the vibrating surface on which ultrasonic vibration is performed is directly contacted with the portion to be cleaned for cleaning.
 また、特許文献3には、洗浄液が流れる流路の一部をなす先細り形状の空洞部を有し、空洞部内の洗浄液を吐出する吐出口を空洞部の先端に有するノズル本体と、超音波振動子の前端面に密着固定され、耐薬品性の非金属無機材料から構成され、かつ、空洞部の内部空間の半分以上の容積を占有する振動体とを備え、振動体の外表面と空洞部の内壁面との隙間を介して、洗浄液が流れるように構成した流水式超音波洗浄機ノズルが開示されている。 Further, Patent Document 3 has a nozzle body having a tapered cavity portion forming a part of a flow path through which a cleaning liquid flows, and having a discharge port for discharging the cleaning liquid in the cavity portion at the tip of the cavity portion, and ultrasonic vibration. It is provided with a vibrating body that is closely fixed to the front end surface of the child, is made of a chemical-resistant non-metallic inorganic material, and occupies more than half the volume of the internal space of the cavity, and the outer surface and cavity of the vibrating body. Disclosed is a running water type ultrasonic cleaner nozzle configured to allow a cleaning liquid to flow through a gap with an inner wall surface of the above.
 特許文献3によれば、流水式超音波洗浄機では、振動体の外表面と空洞部の内壁面との隙間を介して流れる洗浄液が吐出口から流水として吐出され、吐出の際に、超音波振動子及び振動体によって洗浄液に超音波が重畳される。この場合、振動体によって、空洞部の内部空間の大部分があらかじめ埋められている。また、超音波振動子に密着固定された振動体は振動時に負荷となるため、空洞部内が洗浄液で満たされていない状態でも、短時間であれば空焚きを許容することができる。 According to Patent Document 3, in the running water type ultrasonic cleaner, the cleaning liquid flowing through the gap between the outer surface of the vibrating body and the inner wall surface of the cavity is discharged as running water from the discharge port, and the ultrasonic waves are discharged at the time of discharge. Ultrasonic waves are superimposed on the cleaning liquid by the vibrator and the vibrating body. In this case, most of the internal space of the cavity is pre-filled by the vibrating body. Further, since the vibrating body closely fixed to the ultrasonic vibrator becomes a load at the time of vibration, even if the inside of the cavity is not filled with the cleaning liquid, it is possible to allow empty heating for a short time.
 また、振動体を内蔵した他の従来の流水式超音波洗浄装置が知られている。図7は、振動体を内蔵した従来の流水式超音波洗浄装置の構成を示す断面図である。 In addition, other conventional running water type ultrasonic cleaning devices with a built-in vibrating body are known. FIG. 7 is a cross-sectional view showing the configuration of a conventional running water type ultrasonic cleaning device having a built-in vibrating body.
 図7に示すように、流水式超音波洗浄装置80は、筐体81と、筐体81の内部に収納されている振動体84と、振動体84の一方の面に設けられた超音波振動子88と、洗浄液75を供給する給液口82と、流路94の一部を構成するノズル部90とを有している。ノズル部90は、振動体84とともに流路94を構成する。即ち、ノズル部90は、その内側にノズル内壁91を備え、振動体84は、洗浄液75の接触面である外周面87を備え、これらノズル内壁91と外周面87により流路を構成し、給液口82からの洗浄液75は流路94を介して、ノズル内壁91の先端の吐出口92から吐出される。 As shown in FIG. 7, the running water type ultrasonic cleaning device 80 includes a housing 81, a vibrating body 84 housed inside the housing 81, and ultrasonic vibration provided on one surface of the vibrating body 84. It has a child 88, a liquid supply port 82 for supplying the cleaning liquid 75, and a nozzle portion 90 forming a part of the flow path 94. The nozzle portion 90 constitutes the flow path 94 together with the vibrating body 84. That is, the nozzle portion 90 includes a nozzle inner wall 91 inside, and the vibrating body 84 has an outer peripheral surface 87 which is a contact surface of the cleaning liquid 75, and the nozzle inner wall 91 and the outer peripheral surface 87 form a flow path to supply the nozzle portion 90. The cleaning liquid 75 from the liquid port 82 is discharged from the discharge port 92 at the tip of the nozzle inner wall 91 via the flow path 94.
 図7の流水式超音波洗浄装置80は、断面図で示しているが、この場合、スポット状に洗浄液を吐出するスポットシャワー型の流水式超音波洗浄装置として構成する場合の他、ライン上に洗浄液を吐出するラインシャワー型流水式超音波洗浄装置として構成することも可能である。 The running water type ultrasonic cleaning device 80 of FIG. 7 is shown in a cross-sectional view, but in this case, in addition to the case where it is configured as a spot shower type running water type ultrasonic cleaning device that discharges the cleaning liquid in a spot shape, it is on the line. It can also be configured as a line shower type running water type ultrasonic cleaning device that discharges cleaning liquid.
 図7に示すように、振動体84の先端部85に位置し、洗浄液に超音波振動を印加して吐出する振動面86は、吐出口92を形成するノズル内壁91よりも筐体81の内部側に設けられている。また、特許文献3に開示された流水式超音波洗浄機は、振動体の外表面と空洞部の内壁面との隙間を介して流れる洗浄液に超音波が重畳されて、洗浄液が吐出口から流水として吐出される。洗浄液が吐出される吐出口は、ノズル本体の先端に設けられている。 As shown in FIG. 7, the vibrating surface 86 located at the tip end portion 85 of the vibrating body 84 and applying ultrasonic vibration to the cleaning liquid to discharge the vibration surface 86 is inside the housing 81 rather than the nozzle inner wall 91 forming the discharge port 92. It is provided on the side. Further, in the running water type ultrasonic cleaner disclosed in Patent Document 3, ultrasonic waves are superimposed on the cleaning liquid flowing through the gap between the outer surface of the vibrating body and the inner wall surface of the cavity, and the cleaning liquid flows from the discharge port. Is discharged as. The discharge port from which the cleaning liquid is discharged is provided at the tip of the nozzle body.
 このように、図7及び特許文献3に示すように、従来の流水式超音波洗浄装置は、振動体とノズル本体の空洞部とで流路を形成したり、ノズル部90のノズル内壁91と振動体84の外周面87とで流路を形成して、流路からの洗浄液が振動体の先端部に流れて、振動体の先端部の振動面からの洗浄液が吐出口から吐出される。 As described above, as shown in FIG. 7 and Patent Document 3, in the conventional running water type ultrasonic cleaning device, a flow path is formed by the vibrating body and the hollow portion of the nozzle body, and the flow path is formed with the nozzle inner wall 91 of the nozzle portion 90. A flow path is formed by the outer peripheral surface 87 of the vibrating body 84, the cleaning liquid from the flow path flows to the tip portion of the vibrating body, and the cleaning liquid from the vibrating surface of the tip portion of the vibrating body is discharged from the discharge port.

 図7に示す従来の流水式超音波洗浄装置80は、ノズル部90のノズル内壁91と振動体84の外周面87の隙間が流路94を形成しているため、振動体84によって洗浄液75に印加した超音波振動が、洗浄液75を介してノズル内壁91に伝搬してしまう。 In the conventional running water type ultrasonic cleaning device 80 shown in FIG. 7, since the gap between the nozzle inner wall 91 of the nozzle portion 90 and the outer peripheral surface 87 of the vibrating body 84 forms the flow path 94, the vibrating body 84 makes the cleaning liquid 75 into the cleaning liquid 75. The applied ultrasonic vibration propagates to the nozzle inner wall 91 via the cleaning liquid 75.
 これにより、振動体84の振動面86よって洗浄液75に印加した超音波振動がノズル内壁91に伝搬して減衰してしまい、洗浄液75が減衰した状態で吐出口92から被洗浄物77に放出されてしまう。このため、超音波振動が重畳される洗浄液の音圧が低下し、被洗浄物への洗浄作用を弱めてしまう。 As a result, the ultrasonic vibration applied to the cleaning liquid 75 by the vibrating surface 86 of the vibrating body 84 propagates to the nozzle inner wall 91 and is attenuated, and is discharged from the discharge port 92 to the object to be cleaned 77 in a state where the cleaning liquid 75 is attenuated. Will end up. Therefore, the sound pressure of the cleaning liquid on which the ultrasonic vibration is superimposed decreases, and the cleaning action on the object to be cleaned is weakened.
 また、洗浄液75がノズル内壁91を伝って流れることにより、振動体84の先端部85の表面や近傍に気泡が溜まることがある。振動体84の表面に気泡が溜まることにより振動体84が空焚き状態となり、超音波振動子88が故障する可能性がある。 Further, as the cleaning liquid 75 flows along the inner wall 91 of the nozzle, air bubbles may accumulate on or near the surface of the tip portion 85 of the vibrating body 84. The accumulation of air bubbles on the surface of the vibrating body 84 causes the vibrating body 84 to be in an empty-fired state, which may cause the ultrasonic vibrator 88 to fail.
 また、ノズル部90の先端部分の吐出口92の広さによって、以下に示す不具合が発生していた。例えば、吐出口92が広い場合には、吐出する洗浄液75の径や幅が広がることにより振動体84から洗浄液75に伝搬した超音波振動が拡散して、超音波振動の音圧が減衰する。 Further, due to the width of the discharge port 92 at the tip of the nozzle portion 90, the following problems have occurred. For example, when the discharge port 92 is wide, the ultrasonic vibration propagated from the vibrating body 84 to the cleaning liquid 75 is diffused by widening the diameter and width of the cleaning liquid 75 to be discharged, and the sound pressure of the ultrasonic vibration is attenuated.
 さらに、吐出口92が広いため、吐出する洗浄液に拡散、むら等が発生し、これらの乱れを整流するために多くの洗浄液を供給する必要があり、洗浄液の給水量が多くなり、このため多量の洗浄液を消費する。 Further, since the discharge port 92 is wide, diffusion, unevenness, etc. occur in the discharged cleaning liquid, and it is necessary to supply a large amount of cleaning liquid in order to rectify these disturbances, and the amount of water supplied to the cleaning liquid increases, so that a large amount of water is supplied. Consume the cleaning solution.
 一方、吐出口92が狭い場合には、超音波振動が印加された洗浄液が通過しにくくなるため、結果として超音波振動が弱くなり、被洗浄物への洗浄効果が低下する。 On the other hand, when the discharge port 92 is narrow, it becomes difficult for the cleaning liquid to which the ultrasonic vibration is applied to pass through, and as a result, the ultrasonic vibration becomes weak and the cleaning effect on the object to be cleaned is reduced.
 そこで、本発明の超音波シャワー洗浄装置は、発明者らが上記課題を解決すべく、試行錯誤の結果、想起するに至ったものであり、振動体を流路の内部から連続して吐出口の外部に突出するように設けて、吐出口付近のノズル内壁に超音波振動が伝搬することを抑制して、超音波振動の減衰を少なくし、照射する洗浄液の音圧を高くすることができ、かつ、振動体の表面に気泡が溜まりにくいことを可能にしたものである。 Therefore, the ultrasonic shower cleaning device of the present invention has been recollected by the inventors as a result of trial and error in order to solve the above-mentioned problems, and the vibrating body is continuously discharged from the inside of the flow path. It is possible to suppress the propagation of ultrasonic vibration to the inner wall of the nozzle near the discharge port, reduce the attenuation of ultrasonic vibration, and increase the sound pressure of the cleaning liquid to be irradiated. Moreover, it is possible that air bubbles are less likely to accumulate on the surface of the vibrating body.
 従って、本発明の超音波シャワー洗浄装置は、振動体は流路の内部から連続して吐出口の外部に突出するように設けて、超音波振動を効率よく流路の洗浄液に印加して、洗浄液を拡散させることなく被洗浄物にスポット状、ライン状に照射可能な超音波シャワー洗浄装置を提供することを目的とする。 Therefore, in the ultrasonic shower cleaning device of the present invention, the vibrating body is provided so as to continuously project from the inside of the flow path to the outside of the discharge port, and ultrasonic vibration is efficiently applied to the cleaning liquid of the flow path. It is an object of the present invention to provide an ultrasonic shower cleaning device capable of irradiating an object to be cleaned in a spot shape or a line shape without diffusing the cleaning liquid.

A liquid port, a flow path through which the cleaning liquid continuously flows from the liquid supply port, a vibrating body that constitutes a part of the flow path and applies ultrasonic vibration to the cleaning liquid, and a discharge that discharges the cleaning liquid from the flow path. The vibrating body is provided with an outlet, and is characterized in that the vibrating body continuously projects from the inside of the flow path to the outside of the discharge port.
 また、本発明の前記洗浄液は当該振動体の突出方向に沿って流出することを特徴とする。 Further, the cleaning liquid of the present invention is characterized in that it flows out along the projecting direction of the vibrating body.
 また、本発明の前記吐出口は、スポット状に構成され、前記超音波シャワー洗浄装置は、スポットシャワー型であることを特徴とする。 Further, the discharge port of the present invention is configured in a spot shape, and the ultrasonic shower cleaning device is a spot shower type.
 また、本発明の前記振動体は、前記吐出口の内周面から所定の距離を離間して当該吐出口から外部に突出するように配され、前記内周面と前記振動体との間が前記流路となることを特徴とする。 Further, the vibrating body of the present invention is arranged so as to project outward from the discharging port at a predetermined distance from the inner peripheral surface of the discharging port, and the space between the inner peripheral surface and the vibrating body is arranged. It is characterized by being the flow path.
 また、本発明の前記吐出口は、矩形状に構成され、前記超音波シャワー洗浄装置は、ラインシャワー型であることを特徴とする。 Further, the discharge port of the present invention is configured in a rectangular shape, and the ultrasonic shower cleaning device is a line shower type.
 また、本発明の前記振動体は、前記吐出口の長手方向を構成する各々の内面から所定の距離を離間して当該吐出口から外部に突出するように配され、前記各々の内面と前記振動体との間が前記流路となることを特徴とする。 Further, the vibrating body of the present invention is arranged so as to project outward from the discharge port at a predetermined distance from each inner surface constituting the longitudinal direction of the discharge port, and the inner surface of each and the vibration. It is characterized in that the flow path is between the body and the body.
 本発明の超音波シャワー洗浄装置によれば、振動体を流路の内部から連続して吐出口の外部に突出するように設けることにより、吐出口付近のノズル内壁に超音波振動が伝搬することを抑制できるため、超音波振動の減衰を少なくし、照射する洗浄液の音圧を高くすることができ、かつ、振動体の表面に気泡が溜まりにくいことを可能にしたものである。これにより、超音波振動を効率よく流路の洗浄液に印加して、洗浄液を拡散させることなく被洗浄物にスポット状、ライン状に照射可能である。 According to the ultrasonic shower cleaning device of the present invention, the ultrasonic vibration propagates to the inner wall of the nozzle near the discharge port by providing the vibrating body so as to continuously project from the inside of the flow path to the outside of the discharge port. It is possible to reduce the attenuation of ultrasonic vibration, increase the sound pressure of the cleaning liquid to be irradiated, and make it possible that air bubbles are less likely to accumulate on the surface of the vibrating body. As a result, ultrasonic vibration can be efficiently applied to the cleaning liquid in the flow path to irradiate the object to be cleaned in a spot shape or a line shape without diffusing the cleaning liquid.
 即ち、本発明に係る超音波シャワー洗浄装置は、振動体が流路の内部から連続して吐出口の外部に突出するように設け、振動体先端側のノズル部のノズル内壁である内周面を減らし、吐出口までの内周面と振動体の外周面で形成される隙間の流路の長さを短くしたものである。これにより、ノズル内壁の内周面の吐出口までの流路が短くなり、さらに、振動体は吐出口の外部に突出し、吐出口から振動体の外周に沿って洗浄液が接触して流れることにより、振動体によって洗浄液に重畳した超音波振動が吐出口の内周面に伝搬することが少なくなり、伝搬する超音波振動の減衰を減らすことができる。これにより、吐出される洗浄液の音圧を強くすることができるため、洗浄効果を上げることができる。 That is, the ultrasonic shower cleaning device according to the present invention is provided so that the vibrating body continuously protrudes from the inside of the flow path to the outside of the discharge port, and the inner peripheral surface which is the nozzle inner wall of the nozzle portion on the tip side of the vibrating body. The length of the flow path of the gap formed between the inner peripheral surface to the discharge port and the outer peripheral surface of the vibrating body is shortened. As a result, the flow path to the discharge port on the inner peripheral surface of the inner wall of the nozzle is shortened, and the vibrating body protrudes to the outside of the discharging port, and the cleaning liquid comes into contact with and flows from the discharging port along the outer periphery of the vibrating body. The ultrasonic vibration superimposed on the cleaning liquid by the vibrating body is less likely to propagate to the inner peripheral surface of the discharge port, and the attenuation of the propagating ultrasonic vibration can be reduced. As a result, the sound pressure of the discharged cleaning liquid can be increased, so that the cleaning effect can be improved.
 また、従来の超音波シャワー洗浄装置は、振動体の外周面とノズル本体の内壁面との隙間の流路を洗浄液が流れて吐出口から洗浄液が吐出されるため、狭い流路を流れる洗浄液の流速が早くなり、振動体の表面に気泡が溜まることがあった。これに対して、本発明の超音波シャワー洗浄装置は、振動体先端側のノズル内壁の内周面を減らすことにより、ノズル内壁と振動体の先端部に発生する気泡を減らすことができるため、振動体から洗浄液に伝搬した超音波振動が集中して音圧が高くなり、さらに、振動の伝搬を阻害する気泡が溜まりにくいため、空焚きの発生がなく、超音波振動子の故障を予防することができる。 Further, in the conventional ultrasonic shower cleaning device, the cleaning liquid flows through the flow path in the gap between the outer peripheral surface of the vibrating body and the inner wall surface of the nozzle body, and the cleaning liquid is discharged from the discharge port. The flow velocity became faster, and bubbles sometimes accumulated on the surface of the vibrating body. On the other hand, the ultrasonic shower cleaning device of the present invention can reduce the number of air bubbles generated in the inner wall of the nozzle and the tip of the vibrating body by reducing the inner peripheral surface of the inner wall of the nozzle on the tip side of the vibrating body. The ultrasonic vibration propagated from the vibrating body to the cleaning liquid is concentrated and the sound pressure is increased, and since the bubbles that hinder the propagation of the vibration are less likely to accumulate, there is no occurrence of empty heating and the failure of the ultrasonic vibrator is prevented. be able to.
 また、本発明に係るスポットシャワー型の超音波シャワー洗浄装置では、振動体は、吐出口の内周面から所定の距離を離間して吐出口から外部に突出するように配されており、これにより、振動体から洗浄液に伝搬した超音波振動が集中して吐出されるため、洗浄液の径が細くなり、さらに、音圧が高くなるため、洗浄効果を上げることができ、よりスポット的な洗浄効果が得られる。 Further, in the spot shower type ultrasonic shower cleaning device according to the present invention, the vibrating body is arranged so as to project outward from the discharge port at a predetermined distance from the inner peripheral surface of the discharge port. As a result, the ultrasonic vibration propagated from the vibrating body to the cleaning liquid is concentrated and discharged, so that the diameter of the cleaning liquid becomes smaller and the sound pressure becomes higher, so that the cleaning effect can be improved and more spot-like cleaning can be performed. The effect is obtained.
 また、本発明に係るラインシャワー型の超音波シャワー洗浄装置では、振動体が吐出口の長手方向を構成する各々の内面から所定の距離を離間して吐出口から外部に突出するように配されているため、振動体から洗浄液に伝搬した超音波振動が集中して吐出されるため、洗浄液のラインの幅が細くなり、さらに、音圧が高くなるため、洗浄効果を上げることができる。 Further, in the line shower type ultrasonic shower cleaning device according to the present invention, the vibrating body is arranged so as to project outward from the discharge port at a predetermined distance from each inner surface constituting the longitudinal direction of the discharge port. Therefore, the ultrasonic vibration propagated from the vibrating body to the cleaning liquid is concentrated and discharged, so that the width of the cleaning liquid line is narrowed and the sound pressure is increased, so that the cleaning effect can be improved.
 また、本発明のラインシャワー型の超音波シャワー洗浄装置は、振動体が吐出口の長手方向を構成する各々の内面から所定の距離を離間して吐出口から外部に突出するように配されているため、気泡の発生が少なく、洗浄液を洗浄面に均一に照射できるため、各種サイズのガラス基板等の洗浄に好適である。 Further, in the line shower type ultrasonic shower cleaning device of the present invention, the vibrating body is arranged so as to project outward from the discharge port at a predetermined distance from each inner surface constituting the longitudinal direction of the discharge port. Therefore, the generation of bubbles is small and the cleaning liquid can be uniformly applied to the cleaning surface, which is suitable for cleaning glass substrates of various sizes.

 以下図面を参照して、本発明による超音波シャワー洗浄装置を実施するための形態について、図面を参照して説明する。尚、本発明は、超音波振動を効率よく流路の洗浄液に印加して洗浄する超音波シャワー洗浄装置を提供するものであり、特に、洗浄液を拡散させることなく被洗浄物にスポット状、ライン状に強力な超音波振動のエネルギーを有する洗浄液を照射可能にしたものである。 The embodiment for implementing the ultrasonic shower cleaning device according to the present invention will be described with reference to the drawings below. The present invention provides an ultrasonic shower cleaning device that efficiently applies ultrasonic vibration to the cleaning liquid in the flow path for cleaning, and in particular, spots and lines on the object to be cleaned without diffusing the cleaning liquid.

[スポットシャワー型超音波シャワー洗浄装置の構成]
 最初に、洗浄液等の液体に超音波振動を印加して被洗浄物に吐出するスポットシャワー型超音波シャワー洗浄装置の構成について図1を参照して説明する。図1は、本発明によるスポットシャワー型超音波シャワー洗浄装置の構成を示す断面図である。
[Configuration of spot shower type ultrasonic shower cleaning device]
First, the configuration of a spot shower type ultrasonic shower cleaning device that applies ultrasonic vibration to a liquid such as a cleaning liquid and discharges it to an object to be cleaned will be described with reference to FIG. FIG. 1 is a cross-sectional view showing the configuration of a spot shower type ultrasonic shower cleaning device according to the present invention.
 図1に示すように、超音波シャワー洗浄装置1としてのスポットシャワー型超音波シャワー洗浄装置2は、筐体5と、筐体5の内部に設けられ、洗浄液75(図2に示す。)に超音波振動を印加する振動体20と、振動体20に振動を付与する超音波振動子38と、洗浄液75を吐出する吐出口47と、流路48の一部を構成する整流部40と、洗浄液75を供給する給液口16と、を有している。 As shown in FIG. 1, the spot shower type ultrasonic shower cleaning device 2 as the ultrasonic shower cleaning device 1 is provided in the housing 5 and the inside of the housing 5, and is provided in the cleaning liquid 75 (shown in FIG. 2). A vibrating body 20 that applies ultrasonic vibration, an ultrasonic vibrator 38 that applies vibration to the vibrating body 20, a discharge port 47 that discharges a cleaning liquid 75, and a rectifying unit 40 that constitutes a part of a flow path 48. It has a liquid supply port 16 for supplying the cleaning liquid 75.
 スポットシャワー型超音波シャワー洗浄装置2の筐体5は、略円筒状に形成され、その内部に振動体20が収納、固定されている。筐体5の内部における図1の紙面の縦方向の中心付近の壁面には、振動体20を固定する振動体保持部10が、筐体5の内側に向けて段を成しリング状に突起した状態で設けられている。 The housing 5 of the spot shower type ultrasonic shower cleaning device 2 is formed in a substantially cylindrical shape, and the vibrating body 20 is housed and fixed inside the housing 5. On the wall surface near the center of the paper surface in the vertical direction of FIG. 1 inside the housing 5, a vibrating body holding portion 10 for fixing the vibrating body 20 forms a step toward the inside of the housing 5 and protrudes in a ring shape. It is provided in a state of being.
 筐体5の上部には、上蓋6が設けられている。また、筐体5の下部に位置する底部14付近に、洗浄液75を供給する給液口16が設けられている。また、筐体5の底部14の端面には、整流部40が取り付けられている。 An upper lid 6 is provided on the upper part of the housing 5. Further, a liquid supply port 16 for supplying the cleaning liquid 75 is provided near the bottom portion 14 located at the lower portion of the housing 5. Further, a rectifying unit 40 is attached to the end surface of the bottom portion 14 of the housing 5.
 振動体20は、洗浄液75に超音波振動を印加し、超音波振動を印加した洗浄液75を振動体20における先端部34の振動部35から照射するものである。図1に示すように、振動体20は、その上部に円柱形状を成す振動補助部21と、振動補助部21の下部に突起して設けられ、振動体20を筐体5に固定するための鍔部24と、鍔部24の下部に設けられ、逆円錐台の形状を成す振動伝達部28を有している。振動体20は、金属系の材質から成り、例えばSUS、ステンレス、チタン等が用いられている。 The vibrating body 20 applies ultrasonic vibration to the cleaning liquid 75 and irradiates the cleaning liquid 75 to which the ultrasonic vibration is applied from the vibrating portion 35 of the tip portion 34 of the vibrating body 20. As shown in FIG. 1, the vibrating body 20 is provided with a cylindrical vibration assisting portion 21 on the upper portion thereof and a protrusion on the lower portion of the vibrating assisting portion 21, for fixing the vibrating body 20 to the housing 5. It has a collar portion 24 and a vibration transmission portion 28 provided at the lower part of the collar portion 24 and forming an inverted truncated cone shape. The vibrating body 20 is made of a metal-based material, and for example, SUS, stainless steel, titanium, or the like is used.
 振動補助部21の上端22には、超音波振動子38が密着して取り付けられており、超音波振動子38によって振動体20に超音波振動が印加される。振動体20の上端に位置する超音波振動子38は、超音波発振器96(図3に示す。)により高周波電力が供給されて励起し、振動体20に超音波振動を発生させる。 An ultrasonic vibrator 38 is closely attached to the upper end 22 of the vibration assisting portion 21, and ultrasonic vibration is applied to the vibrating body 20 by the ultrasonic vibrator 38. The ultrasonic vibrator 38 located at the upper end of the vibrating body 20 is excited by being supplied with high-frequency power by the ultrasonic oscillator 96 (shown in FIG. 3) to generate ultrasonic vibration in the vibrating body 20.
 超音波振動子38は、BLT(ボルト締めランジュバン振動子)又は板状でセラミックスの材質からなる圧電セラミックスが用いられている。超音波振動子38は、振動体20の上面にボルト締めまたは接着剤によって固定されている。超音波シャワー洗浄装置に使用可能な超音波振動子38の周波数は、20KHzから3MHzであり、通常使用する周波数は、40KHzから200KHzの範囲である。 As the ultrasonic oscillator 38, BLT (bolt-tightened Langevin oscillator) or a plate-shaped piezoelectric ceramic made of a ceramic material is used. The ultrasonic vibrator 38 is fixed to the upper surface of the vibrating body 20 by bolting or an adhesive. The frequency of the ultrasonic vibrator 38 that can be used in the ultrasonic shower cleaning device is 20 KHz to 3 MHz, and the frequency normally used is in the range of 40 KHz to 200 KHz.
 振動体20の振動補助部21は、上端に固着された超音波振動子38からの超音波振動を鍔部24まで伝搬し、鍔部24で振動振幅の大きさが最小となるように設計されており、超音波振動の伝達を補助するものである。 The vibration assisting portion 21 of the vibrating body 20 is designed so that the ultrasonic vibration from the ultrasonic vibrator 38 fixed to the upper end propagates to the flange portion 24, and the magnitude of the vibration amplitude is minimized at the flange portion 24. It assists in the transmission of ultrasonic vibrations.
 振動体20の鍔部24は、振動補助部21の下部において外側に向けて突起して設けられ、フランジ部を成す。振動体20の鍔部24は、振動体20の振動振幅の大きさが最小の節の位置付近に設けられ、振動体20の鍔部24を筐体5の振動体保持部10の上面11に固定する。そのため、振動体保持部10の先端面12は、その上面11が振動体20の鍔部24と連結される位置まで突出すれば足り、振動伝達部28には接触しない。 The flange portion 24 of the vibrating body 20 is provided so as to project outward at the lower portion of the vibration assisting portion 21, and forms a flange portion. The flange portion 24 of the vibrating body 20 is provided near the position of the node where the magnitude of the vibration amplitude of the vibrating body 20 is the minimum, and the flange portion 24 of the vibrating body 20 is placed on the upper surface 11 of the vibrating body holding portion 10 of the housing 5. Fix it. Therefore, it is sufficient that the tip surface 12 of the vibrating body holding portion 10 protrudes to a position where the upper surface 11 thereof is connected to the flange portion 24 of the vibrating body 20, and does not come into contact with the vibration transmitting portion 28.
 振動体20の鍔部24と筐体5の振動体保持部10とは、それぞれとの接触面を接着剤によって固定したり、鍔部24に貫通孔を設け、振動体保持部10にねじ穴を設けてボルトによって固定する。鍔部24を振動体保持部10に固定しても、振動体20の超音波振動が拘束されることが少ないため、振動体20の超音波振動は安定したものとなる。 The flange portion 24 of the vibrating body 20 and the vibrating body holding portion 10 of the housing 5 are fixed to each other with an adhesive, or a through hole is provided in the flange portion 24 and a screw hole is provided in the vibrating body holding portion 10. And fix it with bolts. Even if the flange portion 24 is fixed to the vibrating body holding portion 10, the ultrasonic vibration of the vibrating body 20 is less likely to be constrained, so that the ultrasonic vibration of the vibrating body 20 becomes stable.
 また、振動体20の鍔部24と筐体5の振動体保持部10との固定により洗浄液75の流入が阻止され、振動体20の振動補助部21や超音波振動子38が洗浄液75と接触することがなく、故障を防止することができる。 Further, the inflow of the cleaning liquid 75 is blocked by fixing the flange portion 24 of the vibrating body 20 and the vibrating body holding portion 10 of the housing 5, and the vibration assisting portion 21 of the vibrating body 20 and the ultrasonic vibrator 38 come into contact with the cleaning liquid 75. It is possible to prevent a failure without doing so.
 鍔部24の下部に設けられ、逆円錐台の形状を有する振動伝達部28は、振動体20が洗浄液75に接する箇所であり、逆円錐台の外周面32と、先端部34を有している。外周面32は、先端部34に向かって徐々に先窄まっており、洗浄液75が吐出口47、先端部34に向かって流れる流路48を形成する。振動体20の先端に位置する先端部34は、底面視で円形をなし、縦振動する振動面35を有し、外周面32から流れる洗浄液75に超音波振動を印加する。 The vibration transmitting portion 28 provided in the lower part of the flange portion 24 and having the shape of an inverted truncated cone is a portion where the vibrating body 20 comes into contact with the cleaning liquid 75, and has an outer peripheral surface 32 of the inverted truncated cone and a tip portion 34. There is. The outer peripheral surface 32 is gradually narrowed toward the tip portion 34, and forms a flow path 48 through which the cleaning liquid 75 flows toward the discharge port 47 and the tip portion 34. The tip portion 34 located at the tip of the vibrating body 20 has a vibrating surface 35 that has a circular shape when viewed from the bottom surface and vibrates vertically, and applies ultrasonic vibration to the cleaning liquid 75 flowing from the outer peripheral surface 32.
 振動伝達部28における先端部34の振動面35は、流路48の内部から連続して吐出口47から外部に突出した位置に配され、かつ、超音波振動子38からの振動振幅が大きくなる腹に相当する位置に設けられている。また、振動体20の振動伝達部28は、先端部34に向かって徐々に形状が細くなっているため、超音波振動子38からの振動が増幅されて先端部34の振動面35に伝搬する。これにより、洗浄液75に強力な超音波振動を印加することができる。 The vibration surface 35 of the tip portion 34 of the vibration transmission portion 28 is arranged at a position continuously protruding from the discharge port 47 to the outside from the inside of the flow path 48, and the vibration amplitude from the ultrasonic vibrator 38 becomes large. It is installed at a position corresponding to the abdomen. Further, since the vibration transmitting portion 28 of the vibrating body 20 gradually becomes thinner toward the tip portion 34, the vibration from the ultrasonic vibrator 38 is amplified and propagates to the vibration surface 35 of the tip portion 34. .. As a result, strong ultrasonic vibration can be applied to the cleaning liquid 75.
 筐体5の下部に位置する底部14には、整流部40が設けられている。整流部40は、筐体5の下部に取り付けられ、給液口16から供給される洗浄液75を一時貯留し、振動体20の外周面32の上部に洗浄液75を供給する。 A rectifying unit 40 is provided on the bottom 14 located at the bottom of the housing 5. The rectifying unit 40 is attached to the lower part of the housing 5, temporarily stores the cleaning liquid 75 supplied from the liquid supply port 16, and supplies the cleaning liquid 75 to the upper part of the outer peripheral surface 32 of the vibrating body 20.
 整流部40は、底部41が円環板状の形状を成し、スポットシャワー型超音波シャワー洗浄装置2の上部の方向に向いた(上蓋6の方向に向いた)一方の面41aには、突起部42が形成されている。突起部42は、円環板状の他方の面41bの円孔の端から一方の面41a側に向かって傾斜面43が形成され、傾斜面43によって形成される空間が、逆円錐台を成すように設けられている。突起部42の傾斜面43は、振動体20の外周面32の一部と隙間ができるように、突起部42の断面は略台形形状に形成されている。 The rectifying unit 40 has a bottom 41 having an annular plate shape, and has one surface 41a facing toward the upper part of the spot shower type ultrasonic shower cleaning device 2 (facing toward the upper lid 6). The protrusion 42 is formed. In the protrusion 42, an inclined surface 43 is formed from the end of the circular hole of the other surface 41b in the shape of an annular plate toward the one surface 41a side, and the space formed by the inclined surface 43 forms an inverted truncated cone. It is provided as follows. The inclined surface 43 of the protrusion 42 has a substantially trapezoidal cross section so that a gap is formed with a part of the outer peripheral surface 32 of the vibrating body 20.
 給液口16から供給される洗浄液75は、整流部40における底部41の一方の面41a、底部41の一方の面41aと垂直の面を成す外周面45、突起部42の上面46及び傾斜面43を流れる。これにより、突起部42の外周面45及び上面46と、筐体5の下部の内周面15及び振動体保持部10の下面13により流路48が形成され、さらに、突起部42の傾斜面43と振動体20における振動伝達部28の外周面32とにより流路48が形成される。 The cleaning liquid 75 supplied from the liquid supply port 16 has an outer peripheral surface 45 forming a surface perpendicular to one surface 41a of the bottom portion 41, one surface 41a of the bottom portion 41, an upper surface 46 of the protrusion 42, and an inclined surface in the rectifying unit 40. It flows through 43. As a result, the flow path 48 is formed by the outer peripheral surface 45 and the upper surface 46 of the protrusion 42, the inner peripheral surface 15 at the lower part of the housing 5, and the lower surface 13 of the vibrating body holding portion 10, and further, the inclined surface of the protrusion 42. The flow path 48 is formed by the 43 and the outer peripheral surface 32 of the vibration transmitting portion 28 in the vibrating body 20.
 また、図1に示すように、洗浄液75を吐出する吐出口47は、整流部40における突起部42の傾斜面43と底部41の他方の面41bとの交差する傾斜面43の下端側に位置する。即ち、吐出口47は、傾斜面43の下部の内周面44に設けられている。 Further, as shown in FIG. 1, the discharge port 47 for discharging the cleaning liquid 75 is located on the lower end side of the inclined surface 43 where the inclined surface 43 of the protrusion 42 in the rectifying portion 40 and the other surface 41b of the bottom portion 41 intersect. do. That is, the discharge port 47 is provided on the inner peripheral surface 44 below the inclined surface 43.
 このように、整流部40は、給液口16から供給される洗浄液75を整流部40に設けられた突起部42の上面46からオーバーフローさせて洗浄液75を振動体20に供給するものであり、洗浄液75が供給される給液口16から連続して洗浄液75が流れる流路48の一部を構成している。 As described above, the rectifying unit 40 overflows the cleaning liquid 75 supplied from the liquid supply port 16 from the upper surface 46 of the protrusion 42 provided on the rectifying unit 40, and supplies the cleaning liquid 75 to the vibrating body 20. It constitutes a part of the flow path 48 in which the cleaning liquid 75 continuously flows from the liquid supply port 16 to which the cleaning liquid 75 is supplied.
 また、筐体5の底部14に取り付けられた整流部40は、給液口16からの洗浄液75を一時貯留して、整流部40における突起部42の上面46からから洗浄液75をオーバーフローさせて整流し、均一な流れを形成して振動体20に導出するための一時的な貯留溝としても作用する。 Further, the rectifying unit 40 attached to the bottom 14 of the housing 5 temporarily stores the cleaning liquid 75 from the liquid supply port 16 and overflows the cleaning liquid 75 from the upper surface 46 of the protrusion 42 in the rectifying unit 40 to rectify. It also acts as a temporary reservoir for forming a uniform flow and leading it to the vibrating body 20.
 また、図1に示すように、振動体20は、吐出口47の内周面44から所定の距離を離間して吐出口47から外部に突出するように配されている。 Further, as shown in FIG. 1, the vibrating body 20 is arranged so as to project outward from the discharge port 47 at a predetermined distance from the inner peripheral surface 44 of the discharge port 47.
 このように、図1に振動体20は、給液口16から続く流路48の内部から連続して吐出口47の外部に突出して、洗浄液75が振動体20の突出方向に沿って流出するように設けられている。 As described above, in FIG. 1, the vibrating body 20 continuously protrudes from the inside of the flow path 48 continuing from the liquid supply port 16 to the outside of the discharge port 47, and the cleaning liquid 75 flows out along the protruding direction of the vibrating body 20. It is provided as follows.
 [スポットシャワー型超音波シャワー洗浄装置の洗浄液の流路]
 次に、スポットシャワー型超音波シャワー洗浄装置の洗浄液の流路及び先端部からの洗浄液の被洗浄物への照射について図2を参照して説明する。図2は、図1における洗浄液の流路及び先端部からの洗浄液の照射を示す図である。
[Flower flow path of cleaning liquid for spot shower type ultrasonic shower cleaning device]
Next, the irradiation of the cleaning liquid from the flow path and the tip portion of the cleaning liquid of the spot shower type ultrasonic shower cleaning device to the object to be cleaned will be described with reference to FIG. FIG. 2 is a diagram showing irradiation of the cleaning liquid from the flow path and the tip portion of the cleaning liquid in FIG.
 図1及び図2に示すように、給液口16から供給された洗浄液75は、整流部40の底部41から筐体5の内周面15と整流部40における突起部42の外周面45との間の空間、並びに振動体保持部10の下面13と突起部42の上面46の成す空間を流れ、振動体20の振動伝達部28の上部に供給される。このように、整流部40の突起部42と、振動体保持部10の下面13及び筐体5の下端側の内周面15との成す空間が洗浄液75の流路48の一部を形成している。 As shown in FIGS. 1 and 2, the cleaning liquid 75 supplied from the liquid supply port 16 extends from the bottom 41 of the rectifying portion 40 to the inner peripheral surface 15 of the housing 5 and the outer peripheral surface 45 of the protrusion 42 in the rectifying portion 40. It flows through the space between the space and the space formed by the lower surface 13 of the vibrating body holding portion 10 and the upper surface 46 of the protruding portion 42, and is supplied to the upper part of the vibration transmitting portion 28 of the vibrating body 20. As described above, the space formed by the protrusion 42 of the rectifying portion 40, the lower surface 13 of the vibrating body holding portion 10 and the inner peripheral surface 15 on the lower end side of the housing 5 forms a part of the flow path 48 of the cleaning liquid 75. ing.
 また、振動体20の振動伝達部28の上部に供給される洗浄液75は、振動伝達部28の外周面32と整流部40の内周面44が構成する吐出口47までの空間と、吐出口47から突出している振動伝達部28の先端部34までの外周面32を流れる。 Further, the cleaning liquid 75 supplied to the upper part of the vibration transmission unit 28 of the vibrating body 20 has a space up to the discharge port 47 formed by the outer peripheral surface 32 of the vibration transmission unit 28 and the inner peripheral surface 44 of the rectifying unit 40, and the discharge port. It flows on the outer peripheral surface 32 up to the tip end portion 34 of the vibration transmission portion 28 protruding from 47.
 このように、振動体20の振動伝達部28の外周面32と整流部40の内周面44が構成する吐出口47までの空間と、吐出口47から振動伝達部28の先端部34までの外周面32が流路48の一部を形成する。 In this way, the space from the discharge port 47 to the discharge port 47 formed by the outer peripheral surface 32 of the vibration transmission unit 28 of the vibrating body 20 and the inner peripheral surface 44 of the rectifying unit 40, and from the discharge port 47 to the tip portion 34 of the vibration transmission unit 28. The outer peripheral surface 32 forms a part of the flow path 48.
 流路48を流れて先端部34に流れ込んだ洗浄液75は、振動体20における振動伝達部28の振動面35で超音波振動が印加されて、振動面35と垂直を成す方向に照射される。振動面35から吐出される洗浄液75は、ビーム状の流線となって被洗浄物77に照射される。 The cleaning liquid 75 that has flowed through the flow path 48 and has flowed into the tip portion 34 is irradiated with ultrasonic vibration in a direction perpendicular to the vibrating surface 35 by applying ultrasonic vibration to the vibrating surface 35 of the vibration transmitting portion 28 in the vibrating body 20. The cleaning liquid 75 discharged from the vibrating surface 35 becomes a beam-shaped streamline and irradiates the object to be cleaned 77.
 スポットシャワー型超音波シャワー洗浄装置2は、筐体5の図1及び図2における紙面の縦方向の中心軸が垂直になるように設置した場合に、振動体20の鍔部24の下部25が振動体20における洗浄液75の流路48の最高点の位置となるように、振動体20が筐体5に取り付けられている。 When the spot shower type ultrasonic shower cleaning device 2 is installed so that the vertical central axis of the paper surface in FIGS. 1 and 2 of the housing 5 is vertical, the lower portion 25 of the flange portion 24 of the vibrating body 20 is installed. The vibrating body 20 is attached to the housing 5 so as to be at the highest point of the flow path 48 of the cleaning liquid 75 in the vibrating body 20.
 図1及び図2に示すように、振動体20は、整流部40の内周面44の吐出口47の外部に突出して設けられており、洗浄液75は鍔部24の下面の流路48から連続して吐出口47の外部の振動体20の突出方向に沿って流出して先端部34の振動面35で超音波振動が印加される。 As shown in FIGS. 1 and 2, the vibrating body 20 is provided so as to project to the outside of the discharge port 47 of the inner peripheral surface 44 of the rectifying unit 40, and the cleaning liquid 75 is provided from the flow path 48 on the lower surface of the flange portion 24. It continuously flows out along the protruding direction of the vibrating body 20 outside the discharge port 47, and ultrasonic vibration is applied to the vibrating surface 35 of the tip portion 34.
 これにより、図2に示すように、吐出口47の外部に突出した振動伝達部28の破線で囲む領域Aを流れる洗浄液75は、振動体20の振動伝達部28の外周面32のみに接触し、筐体5、整流部40には接触していないため、超音波振動が洗浄液75を介して筐体5、整流部40に伝搬しないため、超音波振動のロスがなく、洗浄液75に印加される超音波振動の減衰を減らすことができる。 As a result, as shown in FIG. 2, the cleaning liquid 75 flowing through the region A surrounded by the broken line of the vibration transmitting portion 28 protruding to the outside of the discharge port 47 comes into contact with only the outer peripheral surface 32 of the vibration transmitting portion 28 of the vibrating body 20. Since the housing 5 and the rectifying unit 40 are not in contact with each other, the ultrasonic vibration does not propagate to the housing 5 and the rectifying unit 40 via the cleaning liquid 75, so that there is no loss of ultrasonic vibration and the ultrasonic vibration is applied to the cleaning liquid 75. It is possible to reduce the attenuation of ultrasonic vibration.
 また、振動伝達部28の先端部34である振動面35近傍の外周面32が筐体5、整流部40と近接していないため、振動面35近傍の外周面32の周りは、空間のみであり、泡の発生、泡の停滞がないため、空焚き等を防止することができる。また、泡の発生、泡の停滞がないため、振動面35からの超音波振動を洗浄液75に効率よく印加することができる。これにより、振動体20から照射される洗浄液75は強力な超音波振動が印加されたものとなる。 Further, since the outer peripheral surface 32 near the vibration surface 35, which is the tip end portion 34 of the vibration transmission unit 28, is not close to the housing 5 and the rectifying unit 40, the circumference of the outer peripheral surface 32 near the vibration surface 35 is only a space. Since there is no generation of bubbles and no stagnation of bubbles, it is possible to prevent empty heating and the like. Further, since there is no generation of bubbles and no stagnation of bubbles, ultrasonic vibration from the vibration surface 35 can be efficiently applied to the cleaning liquid 75. As a result, the cleaning liquid 75 irradiated from the vibrating body 20 is subjected to strong ultrasonic vibration.
 [洗浄システムの構成]
 次に、超音波シャワー洗浄装置を制御するための洗浄システムの構成について説明する。図3は、スポットシャワー型超音波シャワー洗浄装置を制御する洗浄システムの構成を示す図である。
[Cleaning system configuration]
Next, the configuration of the cleaning system for controlling the ultrasonic shower cleaning device will be described. FIG. 3 is a diagram showing a configuration of a cleaning system that controls a spot shower type ultrasonic shower cleaning device.
 図3に示すように、スポットシャワー型超音波シャワー洗浄装置2の超音波振動子38は、超音波発振器96によって高周波電力が印加されて超音波振動を発生する。スポットシャワー型超音波シャワー洗浄装置2の給液口16には、洗浄液供給バルブ99を介して洗浄液タンク98や工場の用力配管98等から洗浄液75が供給される。 As shown in FIG. 3, the ultrasonic vibrator 38 of the spot shower type ultrasonic shower cleaning device 2 generates ultrasonic vibration by applying high frequency power by the ultrasonic oscillator 96. The cleaning liquid 75 is supplied to the liquid supply port 16 of the spot shower type ultrasonic shower cleaning device 2 from the cleaning liquid tank 98, the power pipe 98 of the factory, or the like via the cleaning liquid supply valve 99.
 また、スポットシャワー型超音波シャワー洗浄装置2は、プログラムを実行可能なコンピュータから構成されて各種処理を行う制御部97によって制御され、制御部97は、超音波発振器96の発振のON・OFF制御、洗浄液供給バルブ99の通水と断水の制御を行う。 Further, the spot shower type ultrasonic shower cleaning device 2 is controlled by a control unit 97 which is composed of a computer capable of executing a program and performs various processes, and the control unit 97 controls ON / OFF of oscillation of the ultrasonic oscillator 96. , Controls the water flow and water cutoff of the cleaning liquid supply valve 99.
 これにより、洗浄装置の自動化も可能である。尚、図3に示す超音波シャワー洗浄装置を制御する洗浄システムの構成は、一例であり、これに限定するものではない。 This makes it possible to automate the cleaning equipment. The configuration of the cleaning system that controls the ultrasonic shower cleaning device shown in FIG. 3 is an example, and is not limited to this.
 [スポットシャワー型超音波シャワー洗浄装置の洗浄液の音圧及び径の大きさ]
 図4及び図5を用いて、本発明のスポットシャワー型超音波シャワー洗浄装置の洗浄液の音圧及び吐出された洗浄液の径の大きさについて説明する。図4は、振動体が吐出口の内部に収納されている状態と、振動体が吐出口の外部に突出した状態との吐出された洗浄液の径の大きさを模式的に表した図であり、(a)は振動体が吐出口の内部に収納されている状態の洗浄液の径の大きさであり、(b)は、振動体が吐出口の外部に突出した状態の洗浄液の径の大きさである。また、図5はスポットシャワー型超音波シャワー洗浄装置における洗浄液の吐出される洗浄液の音圧の大きさを測定した結果をグラフで示した図である。
[Sound pressure and diameter of the cleaning liquid of the spot shower type ultrasonic shower cleaning device]
With reference to FIGS. 4 and 5, the sound pressure of the cleaning liquid of the spot shower type ultrasonic shower cleaning device of the present invention and the size of the diameter of the discharged cleaning liquid will be described. FIG. 4 is a diagram schematically showing the size of the diameter of the discharged cleaning liquid in the state where the vibrating body is housed inside the discharge port and the state where the vibrating body protrudes to the outside of the discharge port. , (A) is the size of the diameter of the cleaning liquid in the state where the vibrating body is housed inside the discharge port, and (b) is the size of the diameter of the cleaning liquid in the state where the vibrating body protrudes to the outside of the discharge port. That's right. Further, FIG. 5 is a graph showing the results of measuring the sound pressure of the cleaning liquid discharged from the spot shower type ultrasonic shower cleaning device.
 この場合、図4においては、振動体84が吐出口92の内部に収納されている状態と、振動体20が吐出口47の外部に突出した状態との両者について、吐出された洗浄液75の径の大きさを模式的に表した。(a)は、図7に示す振動体84が吐出口92の内部に収納されている状態であり、(b)は、図1及び図2に示す振動体20が吐出口47の外部に突出した状態である。また、図5においては、スポットシャワー型超音波シャワー洗浄装置における、振動体が吐出口の内部に収納されている状態と、振動体が吐出口の外部に突出した状態との両者について、超音波発振器の出力に対する吐出される洗浄液の音圧の大きさを測定した結果を示した。 In this case, in FIG. 4, the diameter of the cleaning liquid 75 discharged is obtained in both the state where the vibrating body 84 is housed inside the discharge port 92 and the state where the vibrating body 20 protrudes to the outside of the discharge port 47. The size of is schematically shown. In (a), the vibrating body 84 shown in FIG. 7 is housed inside the discharge port 92, and in (b), the vibrating body 20 shown in FIGS. 1 and 2 protrudes to the outside of the discharge port 47. It is in a state of being. Further, in FIG. 5, in the spot shower type ultrasonic shower cleaning device, ultrasonic waves are obtained for both the state in which the vibrating body is housed inside the discharge port and the state in which the vibrating body protrudes to the outside of the discharge port. The result of measuring the magnitude of the sound pressure of the discharged cleaning liquid with respect to the output of the oscillator is shown.
 スポットシャワー型超音波シャワー洗浄装置における超音波振動子の駆動周波数は約45KHzであり、音圧の測定は、振動体の先端部の振動面から8mm離れた直下に音圧計の測定プローブを設置して行った。 The drive frequency of the ultrasonic transducer in the spot shower type ultrasonic shower cleaning device is about 45 KHz, and the sound pressure is measured by installing the measurement probe of the sound pressure gauge directly below the vibration surface at the tip of the vibrating body. I went.
 即ち、図4(a)のように、図7に示す振動体84が吐出口92の内部に収納されている状態においては、振動体84の先端部85の振動面86(図7)から8mm直下の位置に音圧計の測定プローブを設置して音圧測定を行った。図4(a)におけるh1がこの8mmに該当する。また、図4(b)のように、図1及び図2に示す振動体20の先端部34の振動面35(図1及び図2)から8mm直下の位置に音圧計の測定プローブを設置して音圧測定を行った。図4(b)におけるh2がこの8mmに該当する。 That is, as shown in FIG. 4A, in a state where the vibrating body 84 shown in FIG. 7 is housed inside the discharge port 92, 8 mm from the vibrating surface 86 (FIG. 7) of the tip portion 85 of the vibrating body 84. A measuring probe of a sound pressure gauge was installed at a position directly below to measure the sound pressure. H1 in FIG. 4A corresponds to this 8 mm. Further, as shown in FIG. 4 (b), a measurement probe of a sound pressure gauge is installed at a position 8 mm directly below the vibration surface 35 (FIGS. 1 and 2) of the tip portion 34 of the vibrating body 20 shown in FIGS. 1 and 2. The sound pressure was measured. H2 in FIG. 4B corresponds to this 8 mm.
 尚、8mmは、超音波振動子の駆動周波数の1/4波長の整数倍の長さに相当する距離である。また、超音波発振器の出力が20W(ワット)、30W、50Wにおけるスポットシャワー型超音波シャワー洗浄装置の吐出される洗浄液75の音圧の測定を行った。測定時においては、図4の被洗浄物77は配していない。 Note that 8 mm is a distance corresponding to an integral multiple of the 1/4 wavelength of the drive frequency of the ultrasonic transducer. Further, the sound pressure of the cleaning liquid 75 discharged from the spot shower type ultrasonic shower cleaning device at the output of the ultrasonic oscillator of 20 W (watt), 30 W, and 50 W was measured. At the time of measurement, the object to be cleaned 77 in FIG. 4 is not arranged.
 図5に示すように、スポットシャワー型超音波シャワー洗浄装置の吐出される洗浄液75の音圧の大きさは、超音波発振器の出力が20W(ワット)のときには、振動体84の先端部85が吐出口92の内部に収納されている状態では、47mVであり、振動体20の先端部34が吐出口47の外部に突出した状態では、122mVであった。また、超音波発振器の出力が30W(ワット)のときには、振動体84の先端部85が吐出口92の内部に収納されている状態では、音圧の大きさは42mVであり、振動体20の先端部34が吐出口47の外部に突出した状態では、132mVであった。また、超音波発振器の出力が50W(ワット)のときには、振動体84の先端部85が吐出口92の内部に収納されている状態では、音圧の大きさは31mVであり、振動体20の先端部34が吐出口47の外部に突出した状態では、95mVであった。 As shown in FIG. 5, the magnitude of the sound pressure of the cleaning liquid 75 discharged from the spot shower type ultrasonic shower cleaning device is such that when the output of the ultrasonic oscillator is 20 W (watt), the tip portion 85 of the vibrating body 84 is used. It was 47 mV when it was housed inside the discharge port 92, and 122 mV when the tip portion 34 of the vibrating body 20 protruded to the outside of the discharge port 47. Further, when the output of the ultrasonic oscillator is 30 W (watt), the magnitude of the sound pressure is 42 mV when the tip portion 85 of the vibrating body 84 is housed inside the discharge port 92, and the vibrating body 20 has. When the tip portion 34 protruded to the outside of the discharge port 47, the voltage was 132 mV. Further, when the output of the ultrasonic oscillator is 50 W (watt), the magnitude of the sound pressure is 31 mV when the tip portion 85 of the vibrating body 84 is housed inside the discharge port 92, and the vibrating body 20 has. When the tip portion 34 protruded to the outside of the discharge port 47, the voltage was 95 mV.
 これにより、振動体の先端部から吐出される洗浄液75の超音波振動による音圧は、図1及び図2に示す振動体20が吐出口47の外部に突出したスポットシャワー型超音波シャワー洗浄装置が、振動体84が吐出口92の内部に収納されている従来のスポットシャワー型超音波シャワー洗浄装置(図7に示す。)に対して相対的に約3倍近くの大きさであることが確認された。 As a result, the sound pressure due to the ultrasonic vibration of the cleaning liquid 75 discharged from the tip of the vibrating body is a spot shower type ultrasonic shower cleaning device in which the vibrating body 20 shown in FIGS. 1 and 2 protrudes to the outside of the discharge port 47. However, the vibrating body 84 is about three times as large as the conventional spot shower type ultrasonic shower cleaning device (shown in FIG. 7) housed inside the discharge port 92. confirmed.
 また、図4に示すように、振動体84が吐出口92の内部に収納されている状態(図4(a))での吐出される洗浄液75の径d1の大きさは、約22mmであり、振動体20が吐出口47の外部に突出した状態(図4(b))での吐出される洗浄液75の径d2の大きさは、約14mmであった。 Further, as shown in FIG. 4, the size of the diameter d1 of the cleaning liquid 75 discharged in the state where the vibrating body 84 is housed in the discharge port 92 (FIG. 4A) is about 22 mm. The size of the diameter d2 of the cleaning liquid 75 discharged in a state where the vibrating body 20 protrudes to the outside of the discharge port 47 (FIG. 4B) is about 14 mm.
 これにより、振動体20が吐出口47の外部に突出した状態での吐出される洗浄液75の径の大きさは、振動体84が吐出口92の内部に収納されている状態での吐出される洗浄液75の径の大きさの約64%であった。 As a result, the size of the diameter of the cleaning liquid 75 discharged when the vibrating body 20 protrudes to the outside of the discharge port 47 is such that the vibrating body 84 is discharged while being housed inside the discharge port 92. It was about 64% of the diameter of the cleaning liquid 75.
 このように、振動体20が吐出口47の外部に突出した状態のスポットシャワー型超音波シャワー洗浄装置2は、吐出される洗浄液75の音圧の上昇と相まって、洗浄液75の径が細く、ビーム状の鋭い洗浄液75を得ることができる。このため、被洗浄物77の表面にビーム状の鋭い洗浄液75を照射することが可能であるため、半導体ウェーハの表面、部品等の洗浄に最適である。 As described above, in the spot shower type ultrasonic shower cleaning device 2 in which the vibrating body 20 protrudes to the outside of the discharge port 47, the diameter of the cleaning liquid 75 is small in combination with the increase in the sound pressure of the discharged cleaning liquid 75, and the beam. A sharp cleaning liquid 75 can be obtained. Therefore, since it is possible to irradiate the surface of the object to be cleaned 77 with a sharp beam-shaped cleaning liquid 75, it is most suitable for cleaning the surface of a semiconductor wafer, parts, and the like.
 [ラインシャワー型超音波シャワー洗浄装置の構成]
 次に、ラインシャワー型超音波シャワー洗浄装置について、図6を参照して説明する。図6は、本発明によるラインシャワー型超音波シャワー洗浄装置の構成を示す断面図である。尚、ラインシャワー型超音波シャワー洗浄装置の原理自体は、既に説明した本発明のスポットシャワー型超音波シャワー洗浄装置2の原理と同様であり、細部の構成の説明は省略する。
[Structure of line shower type ultrasonic shower cleaning device]
Next, the line shower type ultrasonic shower cleaning device will be described with reference to FIG. FIG. 6 is a cross-sectional view showing the configuration of the line shower type ultrasonic shower cleaning device according to the present invention. The principle of the line shower type ultrasonic shower cleaning device itself is the same as the principle of the spot shower type ultrasonic shower cleaning device 2 of the present invention described above, and the description of the detailed configuration will be omitted.
 図6に示すように、超音波シャワー洗浄装置1としてのラインシャワー型超音波シャワー洗浄装置3は、筐体50と、筐体50の内部に設けられ、洗浄液75に超音波振動を印加する振動体55と、振動体55に振動を付与する超音波振動子64と、洗浄液75を吐出する吐出口72と、流路74の一部を構成する整流部65と、洗浄液75を供給する給液口53と、を有している。この場合、図6に示すように、ラインシャワー型超音波シャワー洗浄装置3の各構成要素は、給液口53以外、図6の紙面の後方側に連続するライン上に構成されている。以下、給液口53以外のこれら構成要素は図6の紙面の後方側に連続する前提で説明を行う。 As shown in FIG. 6, the line shower type ultrasonic shower cleaning device 3 as the ultrasonic shower cleaning device 1 is provided in the housing 50 and the inside of the housing 50, and is a vibration that applies ultrasonic vibration to the cleaning liquid 75. The body 55, the ultrasonic vibrator 64 that gives vibration to the vibrating body 55, the discharge port 72 that discharges the cleaning liquid 75, the rectifying unit 65 that constitutes a part of the flow path 74, and the supply liquid that supplies the cleaning liquid 75. It has a mouth 53 and. In this case, as shown in FIG. 6, each component of the line shower type ultrasonic shower cleaning device 3 is configured on a continuous line on the rear side of the paper surface of FIG. 6 except for the liquid supply port 53. Hereinafter, these components other than the liquid supply port 53 will be described on the assumption that they are continuous on the rear side of the paper in FIG.

As shown in FIG. 6, the vibrating body 55 has a vibration assisting portion 56 having a rectangular shape formed in a horizontally long rectangular shape in a cross-sectional view of FIG. 6, and a housing under the cross-sectional view of FIG. A flange portion 58 is provided so as to project on both side surfaces in the longitudinal direction of the 50 to fix the vibrating body 55 to the housing 50, and a flange portion 58 is provided at the lower portion of the flange portion 58. It has a vibration transmission unit 60 that constitutes the shape of the above. The vibrating body 55 is made of a metal-based material, and for example, SUS, stainless steel, titanium, or the like is used.
 振動補助部56の上端には、超音波振動子64が密着して取り付けられて、超音波振動子64によって振動体55に超音波振動が印加される。振動体55の上端に位置する超音波振動子64は、超音波発振器により高周波電力が供給されて、振動体55に超音波振動が励起される。 An ultrasonic vibrator 64 is closely attached to the upper end of the vibration assisting portion 56, and ultrasonic vibration is applied to the vibrating body 55 by the ultrasonic vibrator 64. The ultrasonic vibrator 64 located at the upper end of the vibrating body 55 is supplied with high frequency power by the ultrasonic oscillator, and the ultrasonic vibration is excited to the vibrating body 55.
 超音波振動子64は、板状でセラミックスの材質からなる圧電セラミックスが用いられている。尚、超音波振動子64は、板状の圧電セラミックスに限定するものではなく、例えば、BLT(ボルト締めランジュバン振動子)であってもよい。  Piezoelectric ceramics, which is plate-shaped and made of ceramic material, is used for the ultrasonic vibrator 64. The ultrasonic oscillator 64 is not limited to the plate-shaped piezoelectric ceramics, and may be, for example, a BLT (bolt-tightened Langevin oscillator). It was
 筐体50の下端には、整流部65が設けられている。整流部65は、筐体50の対向する長手方向側面の下部にそれぞれ取り付けられ、給液口53から供給される洗浄液75を一時貯留し、振動体55の外周面61の上部に洗浄液75を供給する。 A rectifying unit 65 is provided at the lower end of the housing 50. The rectifying unit 65 is attached to the lower portion of the opposite longitudinal side surface of the housing 50, temporarily stores the cleaning liquid 75 supplied from the liquid supply port 53, and supplies the cleaning liquid 75 to the upper portion of the outer peripheral surface 61 of the vibrating body 55. do.
 整流部65は、底部66が図6の断面視、横長の板状に構成され、その一方の面66aには、突起部67が形成され、突起部67は、底部66の他方の面66bの長手方向の筐体50の内部側の端部から一方の面66aに向かい、そのまま延伸する傾斜面68を構成している。突起部67の傾斜面68は、振動体55の外周面61の一部と隙間ができるように、突起部67の断面が傾斜している。 In the straightening section 65, the bottom portion 66 is formed in the shape of a horizontally long plate in the cross-sectional view of FIG. 6, and the protrusion portion 67 is formed on one surface 66a, and the protrusion portion 67 is formed on the other surface 66b of the bottom portion 66. It constitutes an inclined surface 68 that extends from the inner end of the housing 50 in the longitudinal direction toward one surface 66a as it is. The inclined surface 68 of the protrusion 67 has an inclined cross section of the protrusion 67 so as to form a gap with a part of the outer peripheral surface 61 of the vibrating body 55.
 整流部65は、底部66の一方の面66aと、これと垂直の面を構成する外周面70、突起部67の上面71及び傾斜面68が洗浄液75の流路74の一部を構成する。突起部67の外周面70及び上面71と、筐体50の内周面54及び振動体保持部52の下面により流路74が形成され、さらに、突起部67の傾斜面68と振動体55における振動伝達部60の外周面61とにより流路74が形成される。 In the rectifying unit 65, one surface 66a of the bottom portion 66, an outer peripheral surface 70 forming a surface perpendicular to the surface, an upper surface 71 of the protrusion 67, and an inclined surface 68 form a part of the flow path 74 of the cleaning liquid 75. A flow path 74 is formed by the outer peripheral surface 70 and the upper surface 71 of the protrusion 67, the inner peripheral surface 54 of the housing 50, and the lower surface of the vibrating body holding portion 52, and further, in the inclined surface 68 and the vibrating body 55 of the protrusion 67. A flow path 74 is formed by the outer peripheral surface 61 of the vibration transmitting portion 60.
 また、図6に示すように、洗浄液75を吐出する吐出口72は、整流部65における突起部67の傾斜面68と底部66の他方の面66bとの交差する傾斜面68の端側に位置する。即ち、吐出口72は、傾斜面68の下部の内周面69に設けられている。 Further, as shown in FIG. 6, the discharge port 72 for discharging the cleaning liquid 75 is located on the end side of the inclined surface 68 where the inclined surface 68 of the protrusion 67 in the rectifying portion 65 and the other surface 66b of the bottom portion 66 intersect. do. That is, the discharge port 72 is provided on the inner peripheral surface 69 below the inclined surface 68.
 このように、吐出口72は、図6の紙面の後方側に連続するように、底面視、矩形状に構成され、振動体55は、吐出口72の長手方向を構成し、対向する両内面から所定の距離を離間して吐出口72から、図6の紙面の後方側に連続して外部に突出するように配されている。そのため、吐出口72の長手方向を構成し、対向する両内面と振動体55との間が流路74となる。 In this way, the discharge port 72 is configured in a rectangular shape in a bottom view so as to be continuous with the rear side of the paper surface of FIG. 6, and the vibrating body 55 constitutes the longitudinal direction of the discharge port 72 and both inner surfaces facing each other. It is arranged so as to continuously project outward from the discharge port 72 on the rear side of the paper surface of FIG. 6 at a predetermined distance from the discharge port 72. Therefore, the longitudinal direction of the discharge port 72 is formed, and the flow path 74 is between both inner surfaces facing each other and the vibrating body 55.
 図6に示すように、振動体55は、整流部65の内周面69から、吐出口72の外部に突出して設けられており、洗浄液75は鍔部58の下面の流路74から連続して吐出口72の外部の振動体55の突出方向に沿って流出して先端部62の振動面63で超音波振動が印加される。 As shown in FIG. 6, the vibrating body 55 is provided so as to project from the inner peripheral surface 69 of the rectifying portion 65 to the outside of the discharge port 72, and the cleaning liquid 75 is continuous from the flow path 74 on the lower surface of the flange portion 58. The ultrasonic vibration flows out along the protruding direction of the vibrating body 55 outside the discharge port 72, and ultrasonic vibration is applied to the vibrating surface 63 of the tip portion 62.
 これにより、吐出口72の外部に突出した振動伝達部60の破線で囲む領域Bを流れる洗浄液75は、振動体55の振動伝達部60の外周面61のみに接触し、筐体50、整流部65には接触していないため、超音波振動が洗浄液75を介して筐体50、整流部65に伝搬しないため、超音波振動のロスがなく、洗浄液75に印加される超音波振動の減衰を減らすことができる。 As a result, the cleaning liquid 75 flowing through the region B surrounded by the broken line of the vibration transmitting portion 60 protruding to the outside of the discharge port 72 comes into contact with only the outer peripheral surface 61 of the vibration transmitting portion 60 of the vibrating body 55, and the housing 50 and the rectifying unit. Since it is not in contact with 65, the ultrasonic vibration does not propagate to the housing 50 and the rectifying unit 65 via the cleaning liquid 75, so that there is no loss of ultrasonic vibration and the attenuation of the ultrasonic vibration applied to the cleaning liquid 75 is reduced. Can be reduced.
 また、振動伝達部60の先端部62である振動面63近傍の外周面61が筐体50、整流部65と近接していないため、振動面63近傍の外周面61の周りは、空間のみであり、泡の発生、泡の停滞がないため、空焚き等を防止することができる。また、泡の発生、泡の停滞がないため、振動面63からの超音波振動を洗浄液75に効率よく印加することができる。これにより、振動体55から照射される洗浄液75は強力な超音波振動が印加されたものとなる。 Further, since the outer peripheral surface 61 near the vibration surface 63, which is the tip portion 62 of the vibration transmission unit 60, is not close to the housing 50 and the rectifying unit 65, the circumference of the outer peripheral surface 61 near the vibration surface 63 is only space. Since there is no generation of bubbles and no stagnation of bubbles, it is possible to prevent empty heating and the like. Further, since there is no generation of bubbles and no stagnation of bubbles, ultrasonic vibration from the vibration surface 63 can be efficiently applied to the cleaning liquid 75. As a result, the cleaning liquid 75 irradiated from the vibrating body 55 is subjected to strong ultrasonic vibration.
